Once Pickit is on your computer, you can find pictures with it as described here:

On the Home tab of the Ribbon, in the Pickit section at the far right, select the Free Images button.

The Pickit Free Images task panel opens on the right side of the application window.

On the pink toolbar near the top, use the second tab, the Pickit market, to browse for images.

Pickit lets you browse images in several ways:

There's a search box (callout A in the picture) where you can type keywords such as flower, clipart, and business.

A set of featured collections (B) just below the Search box. The set includes a Clip Art Characters collection.

There are 25 collections (C) organized by Pickit.

There are numerous user collections (D) to browse.

There are 35 categories (E) of images (such animals and pets, cities and places, music and instruments, and transportation) you can choose from at the bottom of the task panel.

New kinds of clip art for Office 365

Office 365 doesn't have traditional clip art anymore, but subscribers get two fresh kinds of art in its place—icons and 3D models, available on the Insert tab of the ribbon, near where the Clip Art button used to be:

Icons are ready-made images that you can insert, pivot, rotate, color, and resize (with no loss of quality).

On the Insert tab of the toolbar ribbon, in the Images section, select Clip Art.

(In Outlook, when you're using the Reading pane, there isn't an Insert menu. Click Pop Out
and then you'll see the Insert menu and the Clip Art icon.)

The Clip Art task panel appears on the right side of the application window.

In the Search for box, type keywords that describe the art you're looking for.

Under Results should be, select the types of media you want included in the search results:

Ensure that Include Bing content is selected if you're connected to the internet and want images from the web included in your search results. *

Turning on this option gives you more search results to choose from. (Otherwise, leave that box cleared, and you'll only receive search results from the pictures installed on your computer by Office 2010.)

Select Go to start the search.

The search results are shown in the task panel.

You can scroll vertically if the results don't all fit in the task pane.

To see a larger version of a thumbnail image in the result list, or to simply see the image if all that is shown is a small red x placeholder, right-click the thumbnail and select Preview/Properties.

While you're in the Preview/Properties window, you can browse through the images by selecting Previous and Next.

To insert a picture in your document, right-click the thumbnail image in the task panel, and select Insert.

Once the image is inserted, you can adjust its placement by selecting it and dragging with the mouse.

When you search for clip art and pictures online, you'll be directed to Bing. You're responsible for respecting copyright, and the license filter in Bing can help you choose which images to use.
